VC dimension stands for Vapnik–Chervonenkis dimension, a measure of model capacity/complexity.

Artificial Neural Networks (ANNs) are computational algorithms inspired by biological neural networks.

One-class SVM is mainly used for anomaly/outlier detection, which falls under unsupervised learning.

For K-Means, the time complexity per iteration is O(kN), where k = number of clusters and N = number of data points.

The forward–backward algorithm in Hidden Markov Models (HMM) is used to compute posterior marginals over hidden states.

Hidden Markov Model (HMM) is a probabilistic model and can be seen as a special case of Conditional Random Fields (CRF).

In FP-Growth, FP stands for Frequent Pattern, used in association rule mining.

• The car’s speed is a continuous variable that depends on the distance from the car ahead.
• To model this relation, we need a method for predicting a continuous outcome.
